    摘要： A catheter with a balloon anchor may be sized to fit through an inner needle and introduced into the patient through the needle. The inner needle may comprise an atraumatic needle with a side port and/or a blunt tip. The catheter may include a radiopaque coil disposed over the distal portion of the catheter body to assist with catheter placement when viewed with fluoroscopy and/or x-ray. The distal portion of the catheter can be very flexible. A balloon inflation tube may terminate proximal to a proximal end of the expandable balloon anchor such that the distal portion of catheter can be flexible. This termination of the inflation tube may also position the inflation tube away from the annulus and nerve roots, so as to avoid irritation of the annulus and rubbing of the nerve roots that may potentially obscure FAD test results.

    摘要： An apparatus includes a projection having a sharpened end portion configured to be inserted through an annulus of an intervertebral disc to define a distracted volume in the annulus. An expandable member is coupled to the projection and defines a longitudinal axis. The expandable member is configured to be expanded from a collapsed configuration to an expanded configuration in a direction substantially perpendicular to the longitudinal axis when at least a portion of the expandable member is disposed within the distracted volume of the annulus of the intervertebral disc. When the expandable member expands, it defines an expanded volume and defines a cross-sectional perimeter while in the expanded configuration. A cannula is configured to be at least partially inserted into the expanded volume. The cannula defines a cross-sectional outer perimeter having no portion extending outside of the cross-sectional perimeter of the expandable member while in its expanded configuration.

    摘要： In one embodiment, an apparatus includes an elongate body having a collapsed configuration and an expanded configuration. The elongate body has a cutting portion at a distal portion of the elongate body, and the cutting portion defines an opening in the elongate body. The distal portion of the elongate body is configured to be inserted into a nucleus of an intervertebral disc when the elongate body is in the collapsed configuration. The cutting portion of the elongate body is configured to disrupt at least a portion of tissue within the nucleus of the intervertebral disc when the elongate body is in the expanded configuration. The elongate body is configured to capture the portion of tissue within the opening of the elongate body when the elongate body is moved from the expanded configuration to the collapsed configuration while disposed within the nucleus of the intervertebral disc.

    摘要： In one embodiment, an apparatus includes a cannula configured to provide percutaneous access to a nucleus of an intervertebral disc, and an elongate body configured to be movably disposed within a lumen of the cannula. The cannula also defines an opening. The elongate body defines an internal passageway and an opening at a distal portion of the elongate body. The internal passageway of the elongate body can be coupled to a suction source. The elongate body has a cutting portion disposed on an edge of the opening of the elongate body and the elongate body is configured to draw a portion of tissue from within the nucleus of the intervertebral disc into the opening of the elongate body when the suction source is activated. The cutting portion is configured to sever the portion of tissue from the remaining tissue when the elongate body is moved relative to the cannula.
